Since we publish docs on merge, we'll need you to use a feature shortcode to hide these fields until next release.

You will likely have to make a copy of the table for each version (doing this in the middle of a table tends to render badly).

Hey @markmandel, thanks for your input.
I copied the tables and wrapped them with shortcode, I hope this is satisfactory.
